What makes you think this? Wides are part of every cricket format, as far as I know.

Usually we don't see much wides in Test cricket as the criteria is wider than limited edition cricket as Philip said. Some balls which are bowled on leg side and are not wide balls and missed by wicket keeper are considered as bye.

In test cricket the laws of cricket definition of a wide ball is used. law 25 wide ball. In that a ball is a wide if it is not possible to play a normal cricket shot from his normal stance.

In ODI and T20 cricket this is modified by an instruction to be very strict on wides, if the batsment can not play a scoring shot it shall be called wide. They also place guidance marks on the pitch to help judge wides. Also generally deliveries down the legside will be wided.

Wides are considered in test matches (and all other cricket) - however, the criteria for a wide in first class cricket and much looser than in one-day cricket; principally the ball has to be much wider than it does in one-day cricket.
